Abstract

This paper designs a multi-point wireless temperature monitoring system based on NRF24L01. The system consists of a master node and three slave nodes. The slave node uses the STM32 CPU to control the temperature sensor DS18B20 to collect temperature, and wirelessly sends the collected temperature data to the master node through the wireless transceiver module NRF24L01, and displays the temperature in real time on the TFT LCD display of the node. The master node uses STM32 CPU to control the wireless transceiver module NRF24L01 to receive the temperature data sent from multiple slave nodes, and at the same time displays the temperature data of multiple slave nodes on the TFT LCD display of this node in real time, if it exceeds the range of the temperature setting value , the monitoring system alarms. The advantage of this design is the use of wireless data transmission, multi-point data collection, avoiding wiring difficulties during wired transmission, and saving resources, and through test verification, the wireless temperature data transmission distance between the master node and the slave node can reach 100 meters , the temperature measurement accuracy is 0.1 °C.
